Power4 I believe opted out at 16MB. So the story about sleeping beauty is true :-). Wouldn't want to manage the 8-32 physical pages of memory through the VM. Paging not an option, file access irrelevant. In that case I agree that it should be handled by a special purpose extension like Seth's patch to cover a 4GB page. Upto 4MB or so I still believe going the other way is proper. More later... thanks for the info. -- -- Hubertus Franke (frankeh@watson.ibm.com) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
